A customisable GitHub action to check the style of Python code with black.

You can use inputs to alter how black will check your code.

This tells black where to look for files to check.

Default: ., i.e. looks for files in the whole repository.

This tells black how long each line of Python code can be.

Default: 81, which is different from black's default of 88.

This tells black which files we should verify the format of.

Default: \.pyi?$, which matches black's default value.

This tells black which files we should ignore.

Default: /(\.direnv|\.eggs|\.git|\.hg|\.mypy_cache|\.nox|\.tox|\.venv|\.svn|_build|buck-out|build|dist)/, which matches black's default value.

Include this in your .github/workflows/main.yaml:

uses: RojerGS/python-black-check@master

or, if you want to override any of the defaults,

uses: RojerGS/python-black-check@master
with:
  line-length: '81'
  path: '.'
  include: 'apps'
  exclude: '(/*.html|/*.mo|/*.po|/*.png|/*.rst)'
